Opensignal has recently published its latest Mobile Network Experience report for Czechia; the definitive guide to understanding the experience on offer from Czechia’s main mobile operators. T-Mobile wins big in this report: it collects our award for Best Network based on its wins for Reliability Experience, Consistent Quality, Download Speed Experience and Coverage. In this analysis, T‑Mobile became the most awarded operator thanks to winning 12 out of a total of 15 categories.
T-Mobile is recognised as a Opensignal Reliability Experience and Consistent Quality winner across both mobile and fixed broadband experience measures. “Our work certainly doesn’t end with winning this award. For us, it is essential that our customers can rely on our network every day. These results confirm that our long‑term investments - amounting to billions of crowns each year – are guided by one clear priority which is delivering the best possible customer experience. Winning in both mobile networks and fixed broadband experience demonstrates that placing customer experience at the core of our strategy – supported by continuous capacity and network modernization – is delivering tangible results. This achievement is also a testament to the relentless dedication, expertise, and commitment of our employees, whose daily efforts ensure that our strategy translates into real, measurable benefits for our customers,” says Carlos Fernandes, Chief Technology Officer of T‑Mobile and Slovak Telekom.
T-Mobile collects more awards than any other operator. It wins four out of five award categories of the Fixed Broadband Experience report. It wins the Upload Speed award outright: T-Mobile users enjoy an average upload speed of 38.5Mbps – far ahead of second-placed other operator, with 21.9 Mbps. The results confirm the long‑term reliability and consistent quality of the connection, which Opensignal measures based on billions of daily automated data tests carried out in users’ everyday network conditions.
